摘要

本文讨论了基于采样伺服格式的系统在读取过程中采用几种信号处理方法记录码的性能。分别研究了4/15码和4/11码的差分检测和PRML方法的误码率。将这些代码的性能与用于连续伺服格式的(2,7)和(1,7)RLL代码进行了比较。仿真结果表明，在数据频率为12mbps .>的情况下，采用PRML方法的4/11码可以较好地与采用PRML方法的(1,7)RLL码竞争

Performance comparisons of recording codes based on sampled servo format

We discuss the performance of recording codes with several signal processing methods at the reading process for a system based on a sampled servo format. Bit error rates for differential detection and PRML methods with the 4/15 and 4/11 codes are investigated, respectively. The performance of these codes are compared with the (2,7) and (1,7)RLL codes which are designed for a continuous servo format. The simulations indicate that the 4/11 code with PRML method can compete favorably with the (1,7)RLL code with PRML method at a data frequency of 12 Mbps.<>
